IMPROVEMENT IN SELF-HEATING SMOQOTHiNG-IRONS.

vSpecication forming part ofLetters Patent No. V17%',643', dated May 23, 1876 application led March 30, 1876.

To tl-l whom it may concern:

Be it known that we, Mrs. MARY P. JACK- SON, of Kennet Square, in the county of Chester and State ofPennsylvania, and Mrs. SARAH P. BALL, of Frankford, in the city and county of Philadelphia, and State aforesaid, have invented certain new and useful Improvements in Smoothing-Irons, of which the following is a specification:

The object of our invention is to provide a smoothing-iron of simple and economical conwhen in use by gas-flames applied to its interior surface, and be thereby maintained at a suitable and constant heat, obviating the necessity of either changing irons or reheating 5 to which ends our improvements consist in the combination of an upper and a lower section, an intermediate inclined web of wire-gauze, and a gas-supply pipe resting upon or near the top of the lower section, and provided with a series of burner-openings contiguous thereto, as hereinafter -more fully set forth.

In the accompanying drawings, Figure l is a vertical longitudinal central section of a smoothing-iron embodying our improvements 5 and Fig. 2, a horizontal section of the same In lthe construction of our improved smoothing-iron, therein shown, an upper section, A, and a lower section, B, are connected by bolts or studs a. and nuts al. The bolts a are screwed -into vertical standards b on the lower section, which maintain the twosections at such distance apart as may be proper to accommodate the internal heating device, pres" ently to be described. A handle, A', of any suitable material or materials, is attached to the upper section. The two sections are substantially similar in form, the lower being of larger dimensions than the upper, and being arranged relatively thereto, so as to project beyond the latter for a greater distance'at thefront of the iron than at the back.

A gas-supply pipe, G, is passed through an opening inthe upper section A, and rests upon or near the top of the lower section B, being bent conforniably with the outline of the latter, and terminating with a blank orprovided with a hinged or pivoted cap or cover, a3.

A web of wire-gauze, D, extends from the upper to the lower section, around the iron, so as ,to completely inclosethel space between the two sections, and is inclined outward from the upper to the low'er, in correspondence with the difference of their dimensions. The i11- clination of the wire-gauze web being greater toward the front end of the iron, Vby reason of the greater projection at that point of the lowersection, a forward and upward draft is induced to support the combustion of the gas, as the products of combustion nd their readiest escape upon the portions of the web having the greatest inclination. We are thus lenabled to provide for supporting combustionand discharging the products without the use of a chimney, by the aid of a medium, which can be conveniently applied, and is of slight weight.

We claim as our invention, and desire to secure byLetters Patent- 1. The combination, with a smoothing iron, composed of the upper and lower sections A B, of the gas-supply pipe C, coiled on the lower section to project the flame on said sec` tion, substantially as set forth. Y

2. The combination, in a smoothing-iron, of the upper section and lower section with intervening space, and an interposed web of wire gauze surrounding and inolosing said space, substantially as set forth.

3. The combination, with a smoothing-iron, 0f a Wire-gauze web, having a greater inclini tion outward toward the front than at the rear of the iron, substantially as set forth.

4. The combination of the upper and lower sections, the interposed wire-gauze web, the gas-supply pipe, having a. series of burneropenings, and an opening and cap for the ignition of the gas, substantially as set forth.
